Our take on the Unlocked Samsung Galaxy S21 Ultra 5G - 128GB - Navy - SM-G998UZBAXAA

The Galaxy S21 Ultra is Samsung's 2021 flagship phone, with a 6.8-inch 1440p AMOLED screen that runs at 120Hz, a 5,000 mAh battery and a quad rear camera built around a 108MP main sensor and two telephoto lenses with 3x and 10x optical zoom. It was the first Galaxy S phone to support the S Pen, sold separately, and it still holds up on screen, zoom and build against newer rivals. Reviewers praised the display and camera flexibility but flagged the size, the weight and the Exynos version's heat and battery drain in some markets. It suits people who want a big, capable Android phone with strong zoom and a stylus option, and who accept a heavier device with only 128GB of storage here.

Questions and answers

Is the Galaxy S21 Ultra still worth buying?
Yes if you want a large 120Hz screen, strong zoom and S Pen support without paying current-flagship money. It no longer gets new Android versions, so weigh that against newer rivals.

Yes, but the S Pen is sold separately and needs a case with a pen slot or a compatible S Pen Pro. It is the first Galaxy S phone with stylus support.

The 5,000 mAh cell lasts most users a full day. Snapdragon versions tend to hold up better under heavy use than Exynos units.

The phone, a USB-C charging cable, a power adapter and a SIM removal tool. No case or S Pen is included.
